Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Wafer Kisses
Ingredients
Directions
Make the batter
Beat the yolks and whites of the eggs separately until stiff.
Rub the sugar and melted butter together until creamy.
Work in the egg yolks, then add the milk, followed by the flour and egg whites.
Bake and shape
Bake in well-buttered wafer irons quickly, browning as little as possible.
Roll the wafers while hot onto a smooth, round stick, carefully slipping it out once they take shape.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites and yolks add lightness and structure, helping the wafers rise and set thin and crisp.
- Flour
- Provides the structure that holds the wafers together once baked and shaped.
- Sugar
- Sweetens the wafers and helps them brown and crisp as they bake.
- Melted butter
- Adds fat for richness and tenderness, and helps prevent the wafers from sticking to the irons.
- Sweet milk
- Adds moisture so the batter pours smoothly and bakes into a tender wafer.
The step that matters
Baking the wafers quickly. Wafers must bake fast in hot, well-buttered irons, browning as little as possible. Over-browning makes them bitter and brittle, and they must be rolled while still hot, before they set and crack.
Swap the nutmeg
How well each one fits the dish's main ingredients (flour, sugar, butter, milk, egg):
- Cinnamonfits better
- Nutmegthe original
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against flour, sugar, butter, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
